Coal Mine Methane Monitoring

Accurate Methane Data for Coal Mining Operations and Emissions Management

Coal mine methane monitoring from satellite and aircraft gives coal mine operators independently measured, facility-level emissions data that cannot be captured through activity-based estimates or periodic ground sampling alone. 

GHGSat has observed coal mine emissions since 2016. Using DATA.SAT satellite monitoring and DATA.AIR targeted airborne surveys; GHGSat detects methane from ventilation shafts, drainage vents, and open pit faces across every major producing region, pinpointing exactly where it is coming from, at what rate, and whether it represents a recovery opportunity or a compliance requirement. This enables operators to move from estimated emissions to observed performance, supporting more informed decisions around methane management, reporting, and recovery planning.


The Challenge

Unquantified Coal Mine Methane Is a Commercial Loss and a Risk

Coal mining operations release large volumes of methane through ventilation systems, drainage shafts, and surface emissions. In many cases, these emissions are not directly measured at the source, making it difficult for operators to identify where methane is concentrated or how it changes over time. 

Independent studies consistently show that observed emissions can differ from activity-based estimates in major coal-producing regions. Direct measurement gives operators a more complete picture of actual site performance, supporting better decisions around recovery planning, reporting, and operational efficiency. The EU Methane Regulation, in force since August 2024, mandates source-level MRV for all coal mines in or supplying to Europe and explicitly establishes a satellite-based monitoring system as the intended verification tool. 

For coal mine operators, direct measurement provides clearer visibility into operational efficiency and identifies where recovery opportunities may exist. Without facility-level data, it is difficult to prioritize mitigation efforts or confirm whether operational changes are delivering real emissions reductions. 


The GHGSat Solution

Accurate Coal Mine Methane Monitoring from Satellite and Aircraft

GHGSat provides accurate methane measurement that captures emissions at the facility level and tracks them over time. Each observation identifies where methane is being emitted and how persistent those emissions are across coal mining operations. This provides coal mine operators with a consistent emissions picture that can be used to support reporting, operational planning, and methane management decisions.

Methane from coal mining represents a recoverable energy stream when captured effectively. Identifying where emissions are strongest and most persistent helps operators understand where further engineering assessment may be warranted for potential capture or utilization opportunities. GHGSat detects coal mine emissions in 48% of satellite observations globally—three times the detection frequency recorded at oil and gas sites.

What Facility-Level Methane Measurement Means for Mining Operations

Build a Measurable Picture of Coal Mine Emissions Performance

GHGSat identifies where methane is emitted across coal mine facilities and tracks how those emissions change over time. This gives operators visibility into which parts of the coal mine are contributing most to emissions and provides a clearer foundation for operational decision-making.

Identify Where Methane Recovery Opportunities May Exist

Coal mine methane represents a recoverable energy stream when sufficiently concentrated. GHGSat data helps operators identify persistent high-emission sources that may warrant further engineering assessment for potential capture or utilization.

Support More Reliable Methane Reporting

Operators can use independently measured data to support emissions reporting under evolving methane regulations and industry frameworks. This helps reduce reliance on estimates and improves confidence in reported figures.

Understand Emissions at the Source Level

Methane emissions can originate from multiple vents, shafts, and diffuse sources. GHGSat identifies where emissions are concentrated across the facility, helping operators prioritize areas for mitigation or operational adjustment.

Build a Consistent Baseline for Coal mine Performance

Historical observations allow operators to track emissions trends over time and compare them against operational changes. This creates a more consistent basis for evaluating whether mitigation efforts are delivering measurable results.

Monitor Legacy and Abandoned Coal mine Emissions

Closed and abandoned coal mines can continue to emit methane long after operations cease. Satellite monitoring helps identify whether emissions persist at inactive sites, supporting better understanding of legacy liabilities.

Case Study

First Satellite Detection of Methane from an Opencast Coal Mine

OPEN-PIT MINING | COAL | KAZAKHSTAN

In October 2021, GHGSat satellites observed methane emissions from an opencast coal mine from space for the first time. Imaging the Ekibastuz coalfield in Kazakhstan—one of the largest opencast operations in the world—GHGSat recorded two distinct plumes of 12,000 kg/hr and 15,553 kg/hr, a combined emission of approximately 27,500 kg/hr, enough to power 726,000 homes annually.

Open-pit coal mines had previously been considered impossible to measure from space because their emissions spread across wide areas rather than from point sources. This case established that GHGSat’s sensors could detect and quantify them—unlocking independent measurement capability for a coal mine category that represents 40% of coal operations globally and had no credible monitoring method prior to this observation.

Largest Single-Facility Methane Release Ever Recorded

UNDERGROUND COAL MINING | COAL | RUSSIA

Confirmed by the UN Environment Programme as the largest single-facility methane release ever traced to a verified source, the event vented gas that could have been captured and used. Instead, it went undetected until a GHGSat satellite passed overhead—released into the atmosphere and unaccounted for in any operator or national inventory. Independent satellite monitoring made the invisible visible. 

Coal mines Are the Most Persistent Methane Emitters in the Global Energy Sector

GHGSAT SCIENCE STUDY | COAL, OIL AND GAS | GLOBAL

A 2023 study led by GHGSat researchers, published in Science, imaged over 3,000 energy facilities worldwide across more than 32,000 satellite observation passes. Coal mines were found to emit methane in 48% of observations—three times the detection rate for oil and gas operations. Coal mines are steady, persistent emitters rather than intermittent ones.

For coal mine operators, this persistence makes satellite surveillance particularly well-suited to building the consistent emissions record that recovery project planning and MRV compliance require. For investors, it means coal mine methane exposure is a recurring, quantifiable feature of the asset class. For governments, it demonstrates that periodic surveys alone cannot capture the persistent, continuous nature of coal mine emissions and that satellite-based MRV provides a more complete basis for national inventory accounting.

FAQ

Frequently Asked Questions

Coal Mine Methane Monitoring, Answered.

Yes. GHGSat made the world’s first satellite detection of methane from an open-pit coal mine in Kazakhstan in 2021, recording combined plumes of over 27,500 kg/hr. Underground coal mine ventilation shafts and drainage vents are detectable as point sources. DATA.SAT operates at 100 kg/hr and 25 m resolution. DATA.AIR airborne surveys extend detection to 3.5 kg/hr for targeted source-level investigation.


GHGSat satellite observations identify which vents and drainage sources carry the largest, most consistent methane flows over time—the starting point for any commercial capture project. DATA.AIR airborne surveys then attribute those flows to specific equipment at sub-meter resolution, enabling operators to size capture infrastructure and build the business case for gas sale, on-site power generation, or VAM abatement.


DATA.SAT is GHGSat’s satellite constellation—daily wide-area coverage at a 100 kg/hr threshold and 25 m resolution, building a persistent emissions record across coal mine portfolios. DATA.AIR is GHGSat’s airborne service—aircraft-deployed, detecting at 3.5 kg/hr at sub-meter resolution, providing source-level attribution for specific vents, shafts, or equipment. Used together, they form a tiered monitoring strategy.


Financial institutions use GHGSat data to screen coal assets before investment or lending decisions, quantify financed methane emissions under PCAF methodology with independently measured facility data, and monitor portfolio holdings for new emission events. Independent satellite data replaces operator-supplied figures in financed emissions calculations, reducing defensibility risk in regulatory and investor disclosures.


Most coal mines calculate emissions using emission factors and activity-based models rather than direct measurement. Satellite observations frequently show material differences between modelled and measured values—in either direction depending on site conditions, vent configuration, and operational activity. The IEA estimates Australian coal mine methane at 1.7 Mt annually against the country’s UNFCCC submission of 1.0 Mt, illustrating how divergence can be significant at the national level. Facility-level satellite measurement provides a more direct and site-specific basis for understanding actual emissions performance.”


Government agencies use GHGSat data as an independent audit layer against operator submissions to identify high-emitting facilities for targeted inspection and to strengthen national greenhouse gas inventories with measurement-based data. The EU Methane Regulation explicitly mandates a satellite-based monitoring system for this purpose. National regulators outside the EU are developing equivalent frameworks based on the same template.
